Impulse Owner’s Manuals

From time to time I get a call or email from someone who has an old Impulse fish finder or Loran-C receiver, and needs an owner’s manual. If you have one of the Impulse models below, click on your model number to download a manual. I’ve provided both high-resolution and low-resolution versions of each manual, in case you value bandwidth more than quality.

If your Impulse product is not listed here, I’m sorry, but I don’t have a manual for it.

The 2800 and the 2800 PLUS were earlier versions of the same design. If you have one of these earlier models, most of the information in the 2801 manual will still apply to your unit, but the manual will also describe some additional features that were added in the later models. The following table shows the differences between the models.

Impulse 2801 Fish Finder Owner’s Manual

Low Resolution PDF: (465.2 kB)

Impulse 2830 Loran-C/Fish Finder
Impulse 2831 Loran-C/Fish Finder

These are the Owner’s Manuals for the Impulse model 2831 Loran-C/Fish Finder. The 2831 incorporated all of the features of both the 2801 Fish Finder and the 3001 Loran-C Receiver.

Rather than publish a separate owner’s manual dedicated to the 2831, Impulse decided to provide two manuals with the product: one for the fish finder features, and the other for the Loran-C features. Therefore, the complete set of owner’s manuals for the 2831 is actually composed of the 2801 Fish Finder Owner’s Manual and the 3001 Loran-C Owner’s Manual.

If you have a 2830 or 2831 product, you will want both of these manuals.

The following table shows the differences between the 2830 and the 2831.

This is the Owner’s Manual for the Impulse model 3001 Loran-C receiver. As far as I can recall, the earlier model 3000 was identical to the 3001 except for the design of the graphic overlay.

Impulse 4040 Touch Screen Loran-C/Fish Finder

This is the Owner’s Manual for the Impulse model 4040 Touch Screen Loran-C/Fish Finder.

I understand there was a later version of the 4040 that connected to external GPS and Flux-gate Compass modules. This manual does not cover the GPS and Compass features.
